    NoRetry,
    FixedDelay {
        delay_ms: u64,
    },
    ExponentialBackoff {

    Fibonacci {

}

The back-off strategy that determines how long to wait between retry attempts.

Variants

NoRetry

Do not retry — fail immediately after the first attempt.

FixedDelay

Wait a constant delay_ms milliseconds between every attempt.

Fields

delay_ms: u64

Constant delay in milliseconds.

ExponentialBackoff

Multiply the previous delay by multiplier each attempt, capped at max_ms.

Fields

initial_ms: u64

Delay before the first retry in milliseconds.

multiplier: f64

Multiplicative factor applied after each attempt.

max_ms: u64

Upper bound on the delay in milliseconds.

LinearBackoff

Increase the delay by increment_ms each attempt, capped at max_ms.

Fields

initial_ms: u64

Delay before the first retry in milliseconds.

increment_ms: u64

Amount added to the previous delay each attempt.

max_ms: u64

Upper bound on the delay in milliseconds.

Fibonacci

Use the Fibonacci sequence as delays (F(1)=initial, F(2)=initial, …), capped at max_ms.

Fields

initial_ms: u64

Seed value for the first two terms of the sequence.

max_ms: u64

Upper bound on the delay in milliseconds.

Trait Implementations

impl Clone for RetryStrategy

fn clone(&self) -> RetryStrategy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RetryStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RetryStrategy

fn eq(&self, other: &RetryStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
